Abstract

Cyclical fluctuations of cerebral blood flow velocity have been reported previously using Doppler ultrasound. The same phenomena was detected during investigations of changes in cerebral blood volume using near infrared spectroscopy. Rhythmic fluctuations of cerebral blood volume at a frequency of 3.5 cycles/minute is reported here.

摘要

先前已有报道使用多普勒超声检测到脑血流速度的周期性波动。在使用近红外光谱法研究脑血容量变化的过程中也检测到了同样的现象。本文报道了脑血容量以每分钟3.5次的频率出现有节奏的波动。
